Expanded vermiculite-based vermiculite board is a core thermal insulation material with a microporous structure formed by high-temperature sintering, featuring outstanding thermal insulation, fire resistance and sound absorption. Its unique pore structure creates numerous micro insulation spaces, greatly enhancing thermal insulation efficiency and keeping equipment and building interiors at a constant temperature, cutting energy use. As an inorganic non-metallic material, it is non-combustible, flame-retardant and smoke-free, complying with strict fire codes for construction and industry. In building steel structure fire protection, it forms a protective layer to delay temperature rise and maintain structural integrity, ensuring safe evacuation. For stoves and fireplaces, it withstands high temperatures, isolates heat effectively, prevents overheating of enclosures and improves safety. In metallurgical engineering, it is used in steel ladle and tundish insulation layers, resisting molten steel erosion and high-temperature oxidation to stabilize processing temperatures and improve product quality. In gas boilers, it reduces heat dissipation, enhances combustion efficiency and lowers fuel consumption. Lightweight yet high-strength, it eases transportation and installation and reduces structural burden. It is corrosion-resistant, moisture-proof and non-deformable, suitable for long-term use in chemical, thermal and other harsh environments. Eco-friendly and non-toxic, it protects human health and the environment. Customizable specifications support personalized design for industrial and construction projects, making it a preferred material for high-efficiency insulation and fire protection.
